Recognising OLL trouble

[Jude]

I have recently learnt all 57 OLLs, thus becoming a 2 looker, but still have some trouble at recognising between different OLLs. I wondered if anyone had any special techniques for recognising etc between different, similar OLLs. Whenever I use numbers to describe OLLs I'm referencing the numbers given at http://www.speedsolving.com/wiki/index.php/OLL

The OLLs I have trouble with are:
- 4 of the 6 "L shapes" OLLs; 49,50,53,54.
- OLLs 3 and 4. With these I can recognise which is which but I always forget which algorithm accompanies which case (I use y r' R U' r U2 r' U' R U' R2' r and it's mirror)
- The "Lightning Bolt Shapes" OLLs; 7,8,11,12
- The "Knight Move Shapes" OLLs; 13,14,15,16

Any help would be much appreciated, Chukk.

ok, with the L shapes, I use algos where the outer line is always facing left, so I just have to look is the L in front or at back and if the corner FRU is facing me with top colour or not, both not hard to see or think about.

for 3 and 4: if you can recognise and set them up, maybe just think about that you have to pull down the oriented corner?

The "Lightning Bolt Shapes": I look where the connected part is (the edge + corner both yellow or whatever) I set them up so that the lonely oriented edge is at UB and the oriented corner either UFL oder UFR (hope you understand) when I got the connected thing facing me I use R U2 R' U2' R' F R F' or mirror and if not I setup the other case (U' r U R' U R' F R F' R U2 r' or mirror)

The "Knight Move Shapes": I always got the bar from left to right and the oriented corner ar UBL or UBR and so I look at the front if the connected thing is left or right.

I hope any of these bad explanations were helpfull and not too confusing, if you got questions I will try to explain it better or whatever...

P.S: Practise practise PRACTISE
I am not that good I think but I thought about what things are significant and as easy to see as possible and it's just setting up the shape to your own picture and then look at one corner or maybe two.

Uh, I don't relaly wanna get into detail. But after a little while you get used to the shapes and are able to recognize them faster.

thats why I don't learn them at once.. I learn some of them and then try to get used to it..

I'm not using OLL but if I did I would look for corners like in Ortega 2x2x2 and then the edges will be wery easy to spot. It makes 8 patterns to recognise and then 8 patterns per pattern.

8 patterns for corners * 8 patterns for edges = 64 OLL minus solved case + a few duplicated cases makes 57.

Sometimes I practice to solve CLL and orient LL edges in one go (same as OLL+CP), then I use that recognition style but then it is 42*8 patterns = 336 but also here there are duplications, have not counted but in total it is like 310 cases or so.

I wouldn't have recommended learning so many algs in such a short amount of time, you should take you time let a few algs "sink in" until you can instantly recognice those cases and perform the algs fluently, then you can move on to other ones

For now, I say it's best to look at the patterns of each case yourself so you'll remember them better. Everyone uses different ways of distinguising the different cases.

 

[Escher]

dammit chukk i knew that learning 57 algs in about a fortnight was inhuman and that you would pay! how about doing those algs over and over and over and over...?

Thanks for the help everyone, especially you're detailed response Cerberus - a few of you're ideas work for me but for most of them I hold my cube differently when performing the algorithm so they don't really apply. I guess maybe learning them in blocks of 10-15 every few days was not a good idea, and I guess I'll just have to go over them repeatedly till I invent my own ways of recognising.
